Image division measurement method and device

The invention relates to the technical field of measurement, in particular to an image division measurement method and a device. The method comprises the steps of capturing images of a measurement surface zonally with a plurality of image capturers, transmitting the captured images into a computer, allowing the computer to process and treat acquired image information, re-modeling to obtain a complete and continuous image of the measurement surface required by a user, and carrying out measurement and conversion according to the complete and continuous image of the measurement surface displayed by the computer to obtain an actual value. The image capturers distributed in an arrayed manner are erected on a movable workbench of the device, and prisms are arranged at the front ends of lenses of the image capturers. The measurement method achieves image division capture and displays the actual, complete and continuous measurement image of an object to be measured via modeling, meets one-time measurement of a measurement article with large area, and has high measurement speed, efficiency and accuracy; the measurement device is simple in structure, easy to manufacture and convenient to use and meets industrial utilization.
